To all whom it may concern Be it known that l, VVALTILER MARTIN, of Bitterteld, a subject of the King of Prussia, and whose post-otlice address is Innere Bismarckstrasse N0. 72, Bitteriield, Kingdom of Prussia, German Empire, have invented new and useful Improvements in Feed-Regulators for Shelling and Defibering Machines, of which the following is a specification.

The present invention relates to an arrangement in shelling and defibering machines working with intermittent charge and discharge. According to the present invention it is possible to subject the material to the treatment by the machine for a longer or shorter time without the speed of the working parts (shell and drum) having to be changed, but to vary the speed of the working members relatively to each other, without the duration of the treatment being affected.

The variation of the duration of the treatment and the regulation of the relative speed of the working parts is necessary in consequence of the fact, that products with strongly adhering shells such as barley, maize, pepper and the like or cotton seed with'fibrous residues attached to them will require a longer and more intense shelling and defibering treatment than products the shells of which surround the kernels loosely only, such as peas, lentils, beans, rice and the like. On the other hand oblong seeds such as barley, wheat, and the like the points of which must not be injured by the treatment in the machine, necessitate that the shell revolving around the drum has a slower speed than with round seed, so that it produces a rolling movement. In both instances the shelling member must however maintain a constant circumferential speed, which has been ascertained by long years of experiences.

The desired effect is obtained according to the present invention by the revolving shell of the machine actuating a pawl lever cooperating with a ratchet wheel, which lever will according to its adjustment advance the ratchet wheel, which controls the entire operating mechanism of the machine, by 1, 2

or more teeth. Thereby the material under treatment is exposed according to requirement to such treatment for a longer or shorter time without the speeds of the work ingaparts (shell and drum) having to be varle Specification of Letters Patent.

Referring to the drawings :Figure 1 is a section illustrating the mechanism according to the invention. Figs. 2 and 3 are side elevations of the machine in different positions, and Fig. iis a detail section illustrating a feature of the operating construction for admitting the material.

In the constructional form shown in these drawings a is the drum, Z) is the shell revolving in an opposite direction, 0 are cone pulleys tor varying the speed of these two members, (Z is the hopper, which will automatically receive the required charges for the machine from a container, and auto1natically convey such charge to the machine. This charging device and also the automatic discharge oi the machine is controlled by a mechanism fitted to the hopper having discharge levers and valves on the revolving shell. On the shell is fitted a stationary roller 0 which at each revolution of the shell will engage a pawl lever j" fitted to the hopper (Z (see Figs. 2 and 3) and thereby give the said pawl lever an oscillating movement. By the movement of this pawl lever f, which has at its upper end a pawl. g, a ratchet wheel It is advanced by means of an adjustable abutment pin 2' by one, two or more teeth according to the stroke of the lever f. In both sides oi the ratchet wheel k are cam grooves K: with eccentric indentures, by which the charging and discharging mechanism of the machine is operated. According to the adjustment of the advance of the ratchet wheel by 1, 2 or more teeth or by double indcntures in the cam grooves it will be possible to vary the (in *ation of the treatment of the material in the machine within very wide limits without the speed of the machine itself having to be changed. On the other hand it may be necessary, as has been hereinbefore stated, to vary the relative speed of the working parts (shell and drum), and the aforedescribed means will allow to control the charging and discharging periods according to requirement.

The feed into the charging hopper d and from the same into the machine is controlled by a swiveling valve in the top oi the hopper (Fig. i), which valve is positively operated by a lever m controlled by the cam groove on the rear side of the ratchet wheel. To the rear side of the ratchet wheel It is attached. a cam disk at or the like, (Fig. l), on which glides a lever 0. This cam disk will raise and lower the lower admission valve,

thereby closing or opening it respectively. The cam disk is so adjusted, with regard to the upper admission valve, that the latter is closed, as soon as the lower valve 2) is opened.

The automatic discharge of the machine is operated in the following manner: In the groove I: cut into the front face of the ratchet wheel h, and having an indenture (Figs. 2 and 3) is guided by means of a stud engaging in said groovea lever s fulcrumed on the pin r. Small rollers 23 and t turning on pins are provided both at the fulcrum of the lever s and at its guided end. lVhen the ratchet wheel has been advanced by the pawl lever 7" so far, that the lever s guided in the cam groove passes the eccentric indenture a, the lever s will be raised according to the depth of said indenture a, (Fig. 3). In consequence thereof a lever '0 fitted to the revolving shell of the machine is swung out, which glides with a projecting lug having the shape of a fishbelly over a roller 25 on lever s. In consequence of this positive guidance on the roller 19 the lever a will be moved a small distance and will thereby actuate the discharge valve 10 pivoted within the shell. For more rapidly discharging the machine a second valve 50 is arranged in the shell diametrically opposite the valve w and operated simultaneously with the first valve by means of the ring 1 and a second lever e. The valves are closed by the lever 22 passing with its projection beneath the stationary roller 2& of the pin 1, whereby the lever is returned into its position closing the valves.

For the proper operation of the whole mechanism it is necessary, that the separate mechanisms for operating the various valves namely: 1. for admitting the material to be treated from a container into the hopper of the machine, 2. for admitting the material from the hopper into the machine, and 3. for discharging the machine after the treatment has been completed cooperate in such a manner, that the intervals are adjusted to'their minimum length, so as to avoid the machine having to run idle.
